Plain English Summary

Background and study aims
A national survey carried out by the French Society of Anesthesia and Critical Care with INSERM showed that 15% of anesthetic acts in France were due to diagnostic procedures. Several authors have raised this issue because of the cost involved at national level. For invasive diagnostic radiology (angiography), the necessity of the presence of an anesthesiologist is highly controversial. The safety aspect is mentioned but it is questionable because accidents are rare (approximately 0.1%) in those procedures. This explains that, in many centres, an anesthesiologist can be reached in case of an incident but is not present during the whole procedure. Another justification is to improve patient comfort and satisfaction. Some patients do not want to be sedated because of the possibility of post interventional drowsiness and legal constraints related to the anesthetic action (visit 48 hours in advance, monitoring for several hours etc). This uncertainty about the desired level of sedation is reflected in a wide range of anesthesia practices, ranging from simple monitoring to deep sedation for arteriography.
Controlled sedation the patient (also called PCS) is a method derived from patient-controlled analgesia or PCA. The advantage of this technique is to control the patient's level of sedation. This study assesses how well the PCS method works.

Who can participate?
Participants aged under 70 years, with ASA physical status below 3, a scheduled cerebral angiography, and a consultation with an anesthetist at least 48 hours before the procedure.

What does the study involve?
61 patients were randomly allocated to one of two groups: receiving propofol-based PCS (n = 33, 15 mg bolus in 9 s) or placebo-based PCS (n = 28, bolus of 1.5 mL of a 20% lipid emulsion in 9 s).

What are the possible benefits and risks of participating?
Possible benefits were an improve experience of the sedation and fast recovery. Potential risks were insufficient sedation or secondary effects of propofol.

Where is the study run from?
France, Public Hospital of Marseille, neuroradiology operating room.

When is the study starting and how long is it expected to run for?
The study started in January 2000 and was expected to last 6 months.

Who is funding the study?
There was institutional funding from AP-HM, Public Hospital of Marseille, Research Department.

Study hypothesis

The aim of this study was to evaluate the difference in patient satisfaction, assessed by a specific and validated scale, using a propofol-based PCS compared to placebo-based PCS for diagnostic cerebral angiography.

Diagnostic cerebral angiography


We randomly assigned 61 patients to receive propofol-based PCS (n = 33, 15 mg bolus in 9 s) or placebo-based PCS (n = 28, bolus of 1.5 mL of a 20% lipid emulsion in 9 s).

Intervention type

Drug names

Primary outcome measure

The main objective was to evaluate whether a propofol-based PCS would lead at least to 20% difference in patients’ satisfaction on the EVAN scale, which was self reported the day after the procedure.

Secondary outcome measures

Secondary objectives were to assess the quality of patient conditioning by the neuroradiologist and the anesthetist and to report possible side effect.
